Nope. They built it themselves.

I do work on this. Your last point is correct (and probably the biggest issue). Others include weather and general vision problems.

It's impressive. Making anything completely driverless working at incredibly high speeds is challenging.

This is a very interesting area of research. The state of the art in motion planning for robotics actually uses multiple heuristics at once with A*.

How far along are you?

Have any publications you could point me to?

If you're interested in A* with humanoid robots, check out my post here:

Take a look at this paper:

Specifically, look at the Martelli G family example.

This isn't true. An admissible heuristic guarantees the optimal solution. With an inconsistent heuristic, A* can re-expand states multiple times, but will still end with an optimal path.

In other words, if the heuristic is consistent, then it implies that A* will expand the optimal number of states.

Totally agree. And when one of the suggestions for porting to Py3 is "Decide if the feature is really that important. Maybe you could drop it?", you know something is wrong.

I took it last semester. Most definitely a trap - Smola is one of those guys who's just too smart to teach. Great material - terrible instruction.

GPS can be used on board to do low earth orbit determination.

His method is a bit more complex, but you eventually need to describe how different frequencies change the characteristics of a system. Initially, it's nice to see impedance in terms of a + bi, but that's not easy to manipulate when you eventually want to know a circuit's behavior at various frequencies.

This is because (a + bi) does not inherently describe the sinusoidal behavior of AC. By changing things into the frequency domain (where writing a phasor implies a driving rotational force at some variable frequency), we can now see how the impedance of an entire system varies as frequency changes.

It's really just a math abstraction. Maybe this analogy is a stretch, but you interface with stacks using push and pop, and there's an inherent size to the stack that you keep in the back of your mind. You don't care about the individual memory addresses and their values, you just want to manipulate the stack such that it doesn't overflow/underflow. Just like AC - you don't care where in the complex plane an impedance is at a given frequency (which would be in terms of a+bi), you'd rather just see how its behavior changes as frequencies vary.

And why do you care about impedances for a whole range of frequencies? One example: http://www.ecoustics.com/electronics/products/articles/13106...

Let's not forget Deep Impact. Flew past two asteroids, and even threw something into the first one while taking pictures (with an incredible autonavigation system). Pretty awesome if you ask me.

I work at NASA, and I like to think that I have a personality...in fact, the center I work at is incredibly relaxed and basically has a collegiate atmosphere.

Another one is flot for jquery.

You can even cut that out by using Vimperator.
